Forecasters are warning that temperatures in parts of the UK reach near 30°C this weekend, ahead of a potential third heatwave this year.

Today, highs of 28°C are expected in the southeast of England, as temperatures across the south stay above 20°C.

Sunday, however, will see highs of 29°C in London but the heat will continue to build into next week as Monday could see highs of 31°C before a possible peak of 34°C later in the week as the UK is gripped by a third heatwave.

While this latest hot spell is not expected to be as intense as the record-breaking heatwave earlier this month which saw a new June record of 37.3°C, it’s predicted to last significantly longer, potentially into the middle of the month.
